Steven Soderbergh’s Magic Mike (out June 29) is based on Channing Tatum’s actual experience as a stripper in his teens. But getting into character for the movie still required some out-of-the-ordinary preparation for the 21 Jump Street star and his costars Matthew McConaughey, Joe Manganiello, and Matt Bomer. Check out this (slightly NSFW) snippet from EW’s raucous roundtable interview with the stars, available on stands this week, before clicking through our exclusive photo gallery.
